Lost Artifact (spoilers)

[Aquarius]

I have a few questions that I was wondering if anyone from Eidos could answer.

Over on the TRC.com forums, we've been having a pretty good discussion going on the Lost Artifact plot. But we're running into a lot of questions. lol

#1 - If Sophia Leigh died in The City, then how did she return in Reunion?

#2 - Who stole the Hand of Rathmore from Willard's Lair?

#3 - Does SLINC in Shakespeare's Cliff stand for Sophia Leigh Inc.? And why is it helping with the excavation?

#4 - Whoever this other Sophia is, how did they find out about the artifact?

Thanks!
